System checks and troubleshooting
Possible causes
Loss of communications
between the EV-1 and ACU, or
EV-2 and drive interface unit.
• Autopilot resets due to an
external event (such as use
of the sleep switch, or faulty
wiring causing the autopilot
components to power cycle).
The EV-1 / EV-2 software has
detected a fault it cannot
recover from, and has reset the
pilot.
Solution
Check all physical data
connections between these
devices, as appropriate.
Check all system wiring,
especially power-related
wiring.
Wait approximately 1 minute
for the EV-1 / EV-2 to reset and
re-initialize.
